DAVID S. HAYES, OF CHICAGO, ILLlNOlS.

SPECIFICATION forming part of Letters Patent No. 391,966, dated October 30, 1888.

Application filed February 24, 1887. Serial No. 228.683. (No model.)

To all whom, it may concern:

Be it known that I, DAvIn S. HAYES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Dry Closet, of which the following is a specification.

My invention relates to dry closets such as .l

can be employed in public buildings at a distance from cities, where water systems are unavailable; and its object is to provide such a closetas willV be easilyada'pted to be located in any part of such building, and will not be liable to return odors or gases into the building. These objects I accomplish by means of the mechanism illustrated in theaccompan ying drawings, wherein- Figure l is a broken perspective view of a small closet with my improvements connected therewith. Fig. 2 is a cross-section of the heating pipe'or line andthe grate-bai s thereon. Fig. 8 is a modification thereof.

Like parts are indicated by the same letters in all the gures.

A is avault, suitably constructed and formed with the solid walls, sides and bottom B B, with the aperture C at one end. This aperture opens into the flue or draftway D.

E is a furnace such as is usually employed for heating large buildings, and it may of course be of any size or description.

F is a smokepipe or flue leading therefrom and passing through the upper part of the vault A, through the aperture C, and thence passing upward through the draftway or flue D.

G G are suitable apartments, having the partitions H H and apertures J J and the lids 1t R.

K K are a series of closely-set grate-bars of any character, size, or shape, and, as shown in the drawings, they may be secured to the flue or pipe F. These grate-bars, with the pipe, are placed immediately under the apertures J J.

L is a stove connected with the flue F by the pipe M. p

N is a heating-pipe, which passes from the furnace and connects in any suitable manner and in any suitable way with the livingrooms, so as conduct the heat thereto.

O is a modification of the pipe, having the grate-bars P l? thereon and the curved upper the vault A, as the exigencies of the case may require.

S is a damper in the pipe F, adapted to close Athe end of the same when the furnace E is out of operation.

The use and operation of my invention are as follows: The structure, as shown in Fig. 1, may be constructed and placed in any part of the building; but it will be ordinarily prefen able to place it in the basement. During the winter, when the large furnace E or any other heating device is used for the building, such furnace or heating device may be connected with the pipe F. It the furnace E is used, this heating-pipe may open direct from the fire thereof, and thus form the lue or smokepassage from such furnace. Thus by the passage ot the smoke and heated gases the pipe F becomes constantly heated. lf thebuilding is heated by steam or hot air, this pipe F, it' desired, could of course be easily connected with such hot-air or steam er hot-water sys tem, and thus will be raised to a high temperature. I do not deem it important to eX- hibit any of these methods of heating the pipe F, because, having shown one device in my drawings, any other would be readily made by an ordinary mechanic. At those seasons of the year when the furnace E will not be employed the damper S is turned and a fire is kept up in the stove L, its smokestack being connected with the pipe F. It will of course be readily seen that by heating the pipe F and its connected grate-bars K K, which are closely connected and receive the contents ofthe closet, the same will be subjected to a constant heat, and will be dried out and evaporated. Itwill be equally clear that the air in the vault A heated by such pipe and grate-bars will have a tendency to escape through the chamber C and pass upward through the liuc D. The supply of air to the vault A is furnished through the apertures J. lhus by the constant passage of the heated iiuid through the pipe F, as indicated bythe arrows, and the passage of the heated air through the chamber C and liuc IOO D, as indicated by the arrows, the contents of the dry closet are dried and evaporated and the gases and odors arising therefrom are discharged through the flue into the open air.

5 If in any case it should be found that the pipe F and the grate-bars K K, as shown in Figs. 1 and 2, do not sufficiently retain the contents ofthe closet, a modification like that shown in Fig. 3 may be substituted.

lo Having thus fully described my invention, the use and operation thereof, the same being free and independent and disconnected from the Ventilating system of the building, what I desire to claim and secure by Letters Patent I5 of the United States is the following:

l. ln a dry closet, the combination of a vault With a heated pipe through which hot air passes, said pipe being fixed beneath the apertures, and grate-bars, which, together with the pipe, receive the contents of the closet4 2o and dry and evaporate the same.

2. In a dry closet, the combination of a furnace with a dry pipe provided with lateral projections and a vault, said pipe passing through the vault and beneath the apertures. 25
